To all whom it may; ooneem:

e it known that a r'itizen of the Visited Sta ociv Point, in the NewYork of t and State of new and nsefni Control Down-es. a skaecifieetion.

The horizoniolly arranged switch lever 1 upright her 2, the usual arm isecured to the is provided with nection 4 lea/ling: (not shown herein Anenclosure of modate the swim which her 3 HINl cous'ho railway owitrh 27to acrom .3 iii/lo." is prmideti hinged arm which enclosure is hereinshown as a cage enclosing the. switoh lover I, which cage has a Hotvertieol hook Wall 5. a semicircular vertieal fr nt wall 6 anti :1suitable roof 7. The seniiwirculur front wall 6 of the cage is providedwith a, door 8 whirl] is held normally open hr :1. suitahlo spring 9,for instanre. A hraoket l0 projecting from an upright 11 Within the ragemay be provided with a latch 12 for violding'ly holding the switch loverI in its dosed position he normally open door 8 is secured to thenormally illlil switch lever no, for instance, by n panl im 1.

.e means which I have ing the cage door closed and permitting the switchlever to he moved to its: open position a t'tor the sw'itrh opera forhas entered e cage is constructed, arranged and operatotl as follows:

he inner member shown for look I 14 of a, hinged arm is position andwhen in its horizontal position the outer end-of the said inner member14 hears against the hurl: f the outer edge of the door 8, Winn the dooris closed. An outer member I of this ingorl arm is hinged at 17 to theouter end of the inner member 14. to swing laterally with respertthereto. the outer enrl of which member 16, when the arm is: in itshorizontal position rests upon a bracket 18 projecting from an upright.19. The lower end of the pin 20 in the free end of theonter member 16 ofthe. hinged arm is arranged to enter o hole 21 in the hrnclret l9. andthe upper cml oi the sai pin projects upwardly when the is in itshorizontal position, sullioient to mmiap the switch lover I when it ismoved to its open position shown in ll lotgh 22 is hinged to the uprightll ill) "allow the switch operator e go. ement with the bracket 18, thuslock inc t e door 8 closed with the switch operator inside the cage. Theswitch operator may then move the switch lever 1 from its closedposition shown in ig. 2. to its open position shoe in Fig. 3. It will beseen that the switch operator is locked in. the cage until he firstmoves the switch lever from its open position to its closed position,permitting him to release the outer member 16 of the hinged arm and foldit against the inner member 14 and then swing the two members upwardlyinto their vertical position where they may be so held by the latch 22.This manipulation of the parts will permit the door 8 to swing open andto leave the cage.

It is evident that various changes may he resorted to in theconstruction. form and ar angement of the several parts without dcparting from the spirit and scope of my invention: hence. I do not wishto limit myself to the particular embodiment herein shown and described.but

What I claim is:

1. Av manually operated switch lever. an enclosure therefor having adoor. a lock for securing the door to the switch lever when the door isopen and the lever is in its closed position. and means requiring theopening of the lock and closing of the door to permit the movingof theswitch lever to its open" position.

2. A manually operated switch lever. an enclosure therefor having adoor. a lock for securing the door to the switch lever when the door isopen and the lever is in its closed position. and means requiring theopening of the lock and closing of the door 10 permit the moving of theswitch lever to its o.en" position and requiring the moving o the switchlever to its closed position to permit the opening of the door.

3. A manually operated switch lever. an enclosure therefor having adoor. and means requiring the closing of the door to permi' the movingof the s itch lever to its open position. said means comprising a hingedarm arranged when in one position to prevent the door from heing openedand when in its other position to permit the door to he opened. saidhinged arm comprising two memhers hinged together.

4. A manually operated switch lever. an enclosure therefor having adoor. and means requiring the closing of the door to permit the movingof the switch lever to its open position. said means comprising a hingedarm arranged when in one position to revent the door from being openedand w en in its other position to permit the door to he opened, saidhinged arm comprising two meuihers hinged together. one member beingarranged to swing laterally and the other member vertically.

5. A manually operated switch lever. an enclosure therefor having adoor, means re quiring the closing of the door to permit the moving ofthe switch lever to its "open" position, said means comprising a hingedarm arranged when in one position in pre vent the door from hcing openedand when in its other position to permit the door to he opened. saidhinged arm comprising two members hinged together, one member helngarranged to swing laterally and the other 'memher vertically. and alatch for removahly holding the hinged arm in its vertical position.

6. A manually operated switch lover. a cage enclosing the same. saidcage having a door. a lock for securing the door to the switch leverwhen the door is open and the lever is in its closcrP positiomand meansrequiring the opening of the lock and closing of the door to permit themoving of the switch lover to its open position 7. A manually operatedswitch lever, a cage enclosing the same. said cage having a door, a lockfor securing the door to the switch lever when the door is open and theposition. and means lever is in its closed requiring the opening of theloci; and clos ing of the door to permit the. moving of the switch lererto its open" position an requiring the moving of the switch lever to itsclose-d position to permit the opening of the door.

8. A. manually operated switch lever. a cage enclosing the same. saidcage having a door. and means requiring the closing of the door topermit the moving oi the switch lever to its open position. said meansom prising a hinged arm arranged when in one position to prevent thedoor from being opened and when in its other position to permit the doorto he opened. said hinged arm comprising two members hinged tonether.

9. A manually operated switch lover. a cage cncloslng' the same, saidcage having a door. and means requiring the closing of the door topermit the moving of the switch lever to its open positi n. said meanscomprising a hinged arm arranged when in one position to prevent thedoor from heing: opened and when in its other position to pen mit thedoor to he opened. said hinged arm c mprising two members hingedtogether. one member lining arranged to swing later ally and the othermemher vertically.

10. A mikiually operated switch lever. a cage enclosing the same. saidcage having a door. means requiring the closing of the door to permitthe moving of rho switch lever to its open position. said meanscomprising a hinged arm arranged when in one position to prevent thedoor from being opened and when in its other position to permit the doorto be opened, said hinged arm ion ill)

comprising two members hinged tog one member being arran ed to SYVII)and the other mem J61 vertical y all? a atoll for relnovably holding thehinged arm in its vertical position.

11. A manually operated cage enclosing the same, said cage h switchlever, a l3tl1 (lay of ether, a normally open door, and means forlocklntering the open door to the switch lever when and the level is inits closed" position.
